cdgregory,
The VB.net you wrote means the following things:
1. Tell Cute Chat find your database connection string from web.config file
2. This entry is located in configuration >> appSettings section of web.config. The name of this entry is "ConnectionString".
So you can create a simple web.config file as followings:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="ConnectionString" value="server=(local)\portal;database=SamplePortal;uid=test;pwd=test" />
</appSettings>
</configuration>
